'FuR-PLUCKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 269,838, dated January 2, 1853.

Application filed September 6, 1882. (No model.)

To all whom it may concmn 1 Be it known that l, ISIDOR DRESDNER, of Brooklyn, in the county ot' Kings and State of New York, have invented a new and useful Improvement in Fur-Pluckiug Machines; and Ido hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings,and to the letters of reference marked thereon, making a part of this specification.

My invention relates to machinery for removing` the master-hairs from pelts; and it has for its object a more perfect, simple, and efficient mechanism for producing expeditiously and neatly the desired result.

It consists mainly in the combination of an oscillating and vertically-reciprocating blade with an elastic roller, so arranged in connection with an endless belt as that the fur-skin being secured upon the belt shall be carried into close proximity to the roller and there doubled or bent back, so as to throw the long stili' master-hairs upon the roller in manner to be caught and held thereon by the edge of the blade until, in the revolution of the roller, they are pulled out from the skin.

It consists, furthermore,in devices for actuating the pluckingblade and for securing the pelt upon the belt, all as hereinafter fully described.

ln the accompanying drawings, Figure l is an elevation of the rear of my improved furplucking machine; Fig. 2, a central longitudinal section thereof; and Fig. 3, a detached view, in perspective, of one of the clamps for securing the pelt upon the endless belt.

The frame of the machine is represented in the drawings-by the letters A A', A being the bed,a nd AA uprightsatoneend thereof,which are connected at the top by a cross-bar, a. Between the uprights an elastic roller, B, is Iiournaled in suitable boxes, C C, which are made to slide verticallyin suitable ways formed in the uprights, and are secured when adjusted by means of set-screws, D. The roller is preferably covered with soft rubber, so as to yield slightly under the pressure of the pluckingblade thereon. and is made to revolve with a constant uniform motion from i'rontto rear by any suitable motive power.

The [ducking-blade E, made of thin steel, is secured to a bar, F, hinged to a cross-head, G,

which travels freely up and down between the uprights A A in suitable ways formed therein or thereon to guide its vertical movements. The blade E is secured to the front face ofthe bar F, so as to drop parallel with the axis of the roller into contact with its periphery in a plane which will intersect the horizontal plane of the axis about two-thirds of the distance from the center to the circumference of the roller. The upper rear edge of the bar F is hinged to the reciprocating cross-head Gr, so that when the blade drops into contact with the surface ot' the roller and, engaging the same, is carried upward by it in its revolution the bar and blade will swing back on its hinges, the cross-head being in the meantime carried up by the movement. l

A spring-plate, I-l, placed over the hinged jointofthe blade-bar with the cross-head, serves to throw back the bladeinto its first position, in readiness to drop vertically upon the roller so soon as, in the revolution ot' the roller, it reaches its highest point and is released therefrom. The blade is lifted at the proper moment and carried down to reengage the roller by means of a crank-shaft, J, rotating in bearings in the uprights A A over the elastic roller B. The crank-shaft is provided with a central crank, J', to which the cross-head G,

carrying the blade-bar F and blade E, is connected by a pittnan-rod K. This rod is made in two telescopic sections, and a spring, L, is interposed between the sections, being confined in the recess of the one, so that the end ofthe other ,may bear thereon, as illustrated in Fig. 2. The crank-shaft may be either geared to the roller by means of a belt or other form of gearing or independently to the master-shaft.

Upon the bed A of the machine, in front of` the rollerB, is placed a movable stand or frame, M, whose uprights serve to support horizontal rollers N O, placed parallel to each other and to the plucking-roller B, and in the same horizontal plane as thelatter.

diameter, while the opposite roller, O, is much larger. Over these rollers is carried an endless belt, P, formed of several layers of soft iexible material, and upon this soft belt the pelt to beplucked is secured by means ofclam ping-plates R R. These plates are of a length somewhat greater than the width ofthe belt,

rlhe roller N, placed i next to the plucking-roller B, is -very small .in

rocV

l and secured by means ofa ring, T, ascrew, or

other suitable device. W'hen the clamps are brought together and secured the portion of the pelt under the clampingplate is, by the pressure ofthe clamp thereon, so stinken into the sot't surface of the belt as that the surl'ace oi' thc plate will not project above the level of the fur, and hence will readily pass between the roller N and the plncking-roller B without in terterence.

The stand M admits of adjustment to and from the roller B, so as to regulate the interval between said roller and the belt, and is so adjusted by means of a screw, U, working through a standard, V, on the t'ront end ot' the bed-plate A. This standard V also admits of vertical adjustment, so as to t-ip the stand vM and so throw the forward end ot'the endless belt nearer or to farther from the plucking-roller. The screw U may be removed and the stand M be Vkept in position by hand or by the pressure ofthe operators body against the front end, in which case a spring, \V, which operates to withdraw the stand from theplucking roller B, is introduced, and the operator actnates said spring in producing the desired adjustment of his endless carrier to the plucking-roller.

lVhen the pelt is properly adjusted upon the belt and the machine set in motion the pelt is carried slowly forward, and in passing over the small roller N is so bent and doubled thereon as to throw out the long master-hairs against t-he face ot' the elastic roller B. As the long hairs t'all upon this roller, the blade E, dropping thereon, will confine them between its edge and the face ofthe roller, and as the roller and blade revolve from the pelt these hairs are pulled out by the movement. In the revolution ofthe roller B the blade E is carried upward thereby, any undue strain being taken up by the spring L in the pitman-connection. The blade is also carried back, the hinged joint of its carryingbar F permitting such a movement; but so soon as the blade has thus moved back into contact with the roller B to pull out the hairs engaged thereby the movement of the crank J upon the shaftJ will operate to lift the blade from the roller. 'lhe action of the spring H and thereby facilitating their engagement by the plucking-blade.

I claim as my inventionl. The combination, in a fur-plucking machine, of an elastic roller, B, a hinged'blade,

E, reciprocating to and from the face of the roller, and a small roller or rounded edge. N, placed parallel with the roller B, over which the pelt x x to be plucked is carried, substatitially in the manner and for the purpose herein set forth.

2. The combination, in a fur-plucking machine, with each other and with a crank-shaft, J, of a reciprocating cross-head, G, pitman K, hinged cross-bar E, spring H, plucking-blade E, and [ducking-roller B, substantially in the manner and for the purpose herein set forth.

3. The combination, with the plucking-roller B, hinged pluckingblade E. reciprocating cross-head G, crank J, and pitman K, of a spring, L, interposed between the pitman and cross-head, substantially in the manner and for the purpose herein set forth.

4. The combination, in a fur-plucking machine, with the plucking-roller B land hinged reciprocating plucking-blade E, of the adjustable fratrie M, adapted to support and hold the pelt to be plucked against said pluckingroller B, substantially in the manner and for the purpose set forth.

5. The combination, in a fur-plucking machine, with a pluckingi-oller, B, and pluekiugblade E,and with a suitable supporting-frame, M, ot' an endless belt, P, substantially in the manner and for the purpose herein set forth.

6. The combination, in a fur-plucking machine, with an endless belt, P, ot' serrated clamping-plates adapted to embrace and close upon the opposite sides of the belt, substatitially in the manner and for the purpose herein set torth.

In testimony whereofI have signed my name to this specilication in the presence of two subscribing witnesses.

ISIDOR DRESDNER.
